The five children of fallen billionaire Sean Quinn and three of their spouses face cross-examination about their assets in the Irish High Court this week.

The Fermanagh businessman’s children, sons-in-law Stephen Kelly and Niall McPartland, as well as Karen Woods — the wife of Sean Quinn Jnr — will be grilled about missing millions in rent money generated from the family's international property group (IPG) as well as salaries they received from Russian companies.

The Irish Bank Resolution Corporation, formerly Anglo, secured orders freezing the Quinns' accounts last July and disputed claims by the Quinns they have provided full disclosure of |accounts and assets.

The bank wants documents relating to control of companies in IPG, as well as assets, bank accounts and documents relating to salaries from Russian IPG companies in 2011 and 2012.

Last summer, daughter Aoife Quinn said their family did not have a “pot of gold” — even though members of the family had drawn down almost €3m in salaries from a Russian company since 2011.
